Do some guys just use filters on apps? Trying to date outside my race in Houston and feeling stuck

I’m a white guy in Houston and I’ve mostly dated women outside my race over the last few years, but on apps it feels like I’m hitting a wall. On Bumble and Hinge I’ll match with women I’m really into, usually Black or Asian women, and the convo goes well at first. Then I’ll notice they stop responding after a day or two, or they unmatch after asking where I’m from or what I do. I’m not offended by that, just trying to figure out if there’s something I’m missing in how I’m coming across. I don’t want to sound clueless, because I know racial bias goes both ways and people have their reasons for being cautious. I also know some apps let people filter or sort by race in sneaky ways, or at least people use cues to decide who’s “dateable” way faster than they admit. I’ve tried keeping my profile pretty normal — no weird selfies, more real-life pics, one with my dog, one at a festival in East Downtown — but maybe I’m giving off some vibe without realizing it. Has anyone had luck actually building genuine connections across race on apps, or is meeting in person just way better?
